Linear Actuators

Festo Corp. (Hauppauge, NY) has introduced the DMES electromechanical linear actuators that provide a feed force of up to 3000 N. The lead screw of the actuators is non-backdriveable, eliminating the need for an additional braking mechanism in vertical applications. The lead screw is integrated within the actuator body, providing enhanced protection, and minimizing risk of premature failure related to contamination from debris. An external metal sealing strip provides additional protection from dirt and dust.

Peristaltic Pump

The Vector Series 3005 peristaltic pump from Wanner Engineering (Minneapolis, MN) features a lubricant-filled cavity for constant lubrication, and is capable of continuous duty pumping of harsh liquids at up to 200 PSI. A roller and shoe design requires less starting torque and creates less abrasion. The pump is available in a range of configurations and flows, and can handle fluids with viscosity to 100,000 cps at temperatures to 180 °F. It also can handle solids to 0.6" and fibers to 4" in length. The pump features heavy-duty roller bearings and isolation of pumped fluid.

Rotary Encoder

Gurley Precision Instruments (Troy, NY) offers the R158 rotary incremental encoder that generates quadrature square waves at up to 1 million counts per revolution. It has an optional temperature range from -40 to 100 °C, and an optional radial/axial load of 60N/40N. A 1/4-cycle gated, once-per-rev index signal or full-cycle sinusoid index is standard. Output options include an RS-422 differential line driver, current-source analog waveforms, or voltage-source analog waveforms.

Slide Latch

The A3 push-to-close slide latch from Southco (Concordville, PA) features a molded thermoplastic body and flexible locking options for secure latching of sheet metal and thin thermoplastic panels. It features an integrated lockplug housing, eliminating the need for a separate key cam lock. Both locking and non-locking versions snap into position in identical-size rectangular installation holes. Panel thicknesses may range from 0.031 to 0.062" and a molded-in spring-tab holds each latch in place. It is made of black ABS with a glass-reinforced nylon lockplug and stainless steel spring.
